Abstract

For more complete description of the Al2O3–HfO2–Gd2O3 phase diagram, three vertical sections are constructed in a wide temperature and composition range. The Gd2О3 and HfO2 corner bisectors explain the mechanisms of Gd2О3 phase transformations, С ⇆ Х ⇆ Н ⇆ А ⇆ B, and interaction in the HfO2 corner of the system. The isopleth at 15% (mol.) HfO2 (15H) shows the Al2O3–HfO2–Gd2O3 constitution in Аl2О3- and Gd2О3-rich regions.
